Transformer Station, Method and Apparatus for a Transformer Station

Abstract

A transformer station, in particular, an offshore transformer station including at least one transformer and at least one transformer cooling unit arranged on at least one side wall of the transformer station or a roof of the transformer station and configured to cool the at least one transformer. The transformer station also includes at least one air deflecting unit arranged on at least one roof edge of the transformer station and / or at least one air deflecting unit arranged on at least one side edge of the transformer station. The air deflecting unit is arranged such that an air movement is deflectable in the direction of the transformer cooling unit.

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS[0001]This patent application is a continuation of PCT / EP2017 / 078733, filed Nov. 9, 2017, which claims priority to German Application No. 10 2016 125 375.8, filed Dec. 22, 2016, the entire teachings and disclosure of which are incorporated herein by reference thereto.FIELD[0002]The invention relates to a transformer station, in particular, an offshore transformer station, comprising at least one transformer and at least one transformer cooling unit arranged on at least one side wall or roof of the transformer station and configured to cool the at least one transformer. In addition, the invention relates to a method and an apparatus for a transformer station.BACKGROUND[0003]Nowadays wind energy systems are increasingly used for the production of electrical energy. So called offshore wind energy systems are preferred. The reason for this is that compared to onshore wind energy systems, the expected average wind speed and thus the expected ...

AI Technical Summary

Benefits of technology

The patent describes a new way to cool down transformers in wind farms using the wind that blows through the area. By using an air deflecting unit, the wind can be directed to cool the transformers more efficiently. This allows for smaller and less expensive cooling units to be used, while still ensuring operational safety. The air deflecting unit can be adjusted to change the air duct and maximize the cooling effect. Additionally, the patent also mentions the use of a measuring unit and control device to adjust the current fed into the transformer based on relevant parameters, such as temperature and wind direction, to further increase operational safety and maximize the output power of the wind farm without damaging the transformer.

Problems solved by technology

The reason for this is that the relevant design standard does not (sufficiently) take cooling by wind into account.

This leads to over dimensioning, unnecessary space requirements on the transformer station and thus unnecessarily high costs for the steel structure of the transformer station and its foundation, its installation and the acquisition costs of the transformers.
